Heavy Density White Silica Gel is designed with extremely fine pores which account for its high adsorption capacity over a wide range of humidity. The White Silica Gel when fully activated will dry air and other gases to the order of below 10 ppm. The White Silica Gel corresponds to a dew point of less than -40 degree C. The Heavy Density White Silica Gel is also suitable to be used for liquid phase operations.
